But each user will be expecting different values. For example "scrollamount='2'" set in marquee tag may not be suitable for all users. Some people will expect more speed of scrolling and some other will expect slow movement.
You can experience it using the quote displaying on top of our blog. Currently it is working on FireFox only, it is not working in IE (internet explorer).
<marquee id="quote" scrollamount="2" onDblClick="resetvalue(this);" scrolldelay="0"
onClick="changevalue(this);">scrolling text will come here... </marquee>
